On Windows, Ctrl-F7 (which is the same as the VS default). 7" On Linux, <Leader>o, which is \o by default ("o"=creates .o files) 8" 9" Adds a "Build this target" function, using ninja. This is not bound 10" to any key by default, but can be used via the :CrBuild command. 11" It builds 'd8' by default, but :CrBuild target1 target2 etc works as well, 12" i.e. :CrBuild all or :CrBuild d8 cctest unittests. 13" 14" Requires that gyp has already generated build.ninja files, and that ninja is 15" in your path (which it is automatically if depot_tools is in your path). 16" Bumps the number of parallel jobs in ninja automatically if goma is 17" detected. 18" 19" Add the following to your .vimrc file: 20" so /path/to/src/tools/vim/ninja-build.vim 21 22python << endpython 23import os 24import vim 25 26 27def path_to_current_buffer(): 28 """Returns the absolute path of the current buffer.""" 29 return vim.current.buffer.name 30 31 32def path_to_source_root(): 33 """Returns the absolute path to the V8 source root.""" 34 candidate = os.path.dirname(path_to_current_buffer()) 35 # This is a list of files that need to identify the src directory.
